Parabilis Medicines ^{Priced, Nasdaq: PBLS}

We are a clinical-stage biopharmaceutical company built to develop transformative medicines addressing some of the most consequential, yet historically undruggable, protein targets driving human disease. We leverage our proprietary platform to pioneer a novel therapeutic modality, Helicons, which are stabilized helical peptides engineered to bind and precisely modulate proteins that have long been beyond the reach of conventional medicines. To our knowledge, our lead product candidate, zolucatetide, is the first-ever drug to directly target the interaction between b-catenin and the T-cell factor (“TCF”) family of transcription factors. This is the central node in the Wnt/b-catenin cell signaling pathway, which regulates cell proliferation and differentiation and whose hyperactivation is a driver of millions of cancer cases annually across many tumor types. Zolucatetide has been evaluated in over 150 patients to date and has generated promising clinical data in a range of solid tumors driven by alterations in the Wnt/b-catenin pathway. In our lead indication, desmoid tumors, we have observed tumor reductions in 100% of patients with a 74% objective response rate (“ORR”) in patients who have had at least two post-baseline scans. We plan to initiate a global registrational Phase 3 trial for zolucatetide in patients with desmoid tumors in the first half of 2027.
